Clean Memory

Single Page Applications (SPAs) are prone to memory leaks because the 'Page' never truly reloads. In Blazor, you must be disciplined about disposing of resources.

1. IDisposable and IAsyncDisposable

Always implement IDisposable if your component subscribes to events, creates JS Interop references, or uses timers. If you don't 'Unsubscribe' in the Dispose method, the component will stay in memory forever, even after the user navigates away, because the event publisher still holds a reference to it.

2. The 'Static' Event Trap

A classic leak: Subscribing to a static Action or EventHandler. Since the static object lives for the entire lifetime of the app, it will 'anchor' every component that ever subscribed to it, leading to a steady increase in RAM usage until the browser tab crashes.

3. Architect Insight

Q: "How do I find leaks in Blazor?"

Architect Answer: "Use the browser's **Memory Profiler** (Chrome/Edge DevTools). Take a 'Heap Snapshot', navigate around your app, and then take another snapshot. Use the 'Comparison' view to see which objects (like your components) are still in memory when they should have been destroyed. If you see 100 instances of ProductDetails.razor, you have an event subscription leak."
